Human-in-the-Loop Approval Workflows

This post details the application of the Temporal Validated Pattern to build a robust human-in-the-loop approval system. It addresses common failure modes in document approval processes, such as unanswered requests, silent deadline misses, lost context across restarts, and incomplete audit trails. The solution leverages Temporal's durable execution to ensure decisions are waited on durably, SLAs are enforced automatically, escalations occur without explicit schedulers, and all actions are recorded reliably, even during infrastructure disruptions.
